PIERRE VAUCIIEY AND JULES GILBERT DURAND DE MIOMANDRE, OF MARSEILLES, FRANCE.

APPARATUS FOR EXTRACTING OIL.

SPECIFICATION forming part of Letters Patent No. 588,299, dated August 1'7, 1897.

Application filed October 19, 1896. Serial No. 609,371. (No model.) Patented in France April 20, 1896, No. 255,671.

To zItZZ whom, it may concern.-

Be it known that we, PIERRE VAUOHEY and J ULEs GILBERT D-URAND DE MIOMANDRE, citi- Zens of the French Republic, residing at Marseilles, France, have invented certain new and useful Improvements in Extracting Apparatus, (for which We have obtained Letters Patent in France, No. 255,671, dated April 20, 1896,) of which the following is a full, clear, and exact description.

Our invention has relation to extracting apparatus adapted for extraetin g various materials for use in the arts, sciences, and industries, such as various fatty substances, vegetable and mineral oils, vegetable wax, resinous substances, gums, &c.; and among the objects in View is to provide a simple and inexpensive apparatus Which is economical and efficientin its Working, and with the described objects in view The invention consists in the novel construction, arrangement, and combination of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the appended claim.

In the drawings, Figure 1 is an elevation of an apparatus constructed in accordance with our invention. Fig. 2 is a vertical sectional elevation of the same.

In carrying out our invention we provide a casing or receiver A, of suitable material and dimensions and shape, and within the same we arrange a second receiver B, which is of somewhat less diameter than the receiver A to leave an intermediate space K. The receiver B is adapted, when arranged in the receiver A, to make a tight joint or lit at the top and bottom with the latter for an obvious purpose.

The lower end of the receiver B is hermetically closed by a bottom cover 0, while the upper part of the receiver B is closed similarly by a cover 0. These covers are adapted in practice to form a tight closure of the receiver when in place thereon, but they are also adapted to be removed from said receiver when it is desired to remove the exhausted material from the receiver A and to recharge the latter with fresh material.

The receiver B has its circumferential walls or sides perforated, as shown, and said receiver is adapted to contain the material to be operated upon, while the space K between receiver A and receiver B is intended to contain the extracted matter.

The receiver B is provided with a suitable outlet-pipe for the solvent-as, for instance, the pipe H near its upper edge, which pipe extends through the receiver A and leads off to a suitable condenser, into which latter said pipe II is intended to conduct the steam.

M M indicate suitable inletpipes for the solvent, (as benzin,) the pipe M being valved and extending into the upper interior of the receiver B, while the pipe ll leads into the receiver A at its upper part. The pipe M should in practice he provided in some portion of its length with a valve or cook.

The material to be treated is adapted to be heated, for which purpose any suitable arrangement of heating means may be used. We show a pipe D, which enters the receiver A and extends through the receiver B, preferably in a more or less irregular or devi ated course to give greater heating-surface, and finally passes out of said receiver A after traversing the receiver B. The said pipe D is adapted to conduct the heating medium, as steam, through the apparatus in order that it may exert a heating action upon the material contained in receiver B.

E is a valve in pipe D.

The inner wall of the receiver B may be provided with a filtering-cloth of fabric or of metal arranged along its sides, whereby the dissolved matter will be more or less filtered before leaving the apparatus.

The receiver A is provided with an outlet pipe for the extracted matter, and we employ a pipe for this purpose, the same being in three sections F, F, and F The sections F and F are of metal, while the intermediate section is of glass, whereby the operator can readily determine by the color of the outflowing matter whether or not the same contains any longer dissolved oils or fats or other extract. The section F is provided with a suitable valve or cock, as shown.

J is a gage to determine the level. of the extracted matter and solvent, and G is a steaminlet pipe for the receiver A.

The operation of our apparatus is as follows: The cover O is removed and the material to be treated, which has preferably been previously pulverized or commi-nuted, is placed within the receiver B until said material reaches a height not exceeding the level of the pipe H. The cover C is then arranged upon the receiver 13 to tightly close the same. The valve E is now opened and steam allowed to pass through the pipe D, and when a somewhat high temperature (say about 60 or 7 0 centigrade) is reached the valve E is closed and the solvent introduced through pipes M M and allowed to act upon the material to dissolve the soluble substance contained there in and the dissolved matter allowed from time to time to flow out through outlet-pipe F, which may conduct it to a distilling apparatus. \Vhen the solution passing through the outlet-pipe F becomes colorless, (provided the extracted substance has more or less color,) the operation is finished. If the extracted matter is devoid of color in itself, then the completion of the extracting process may be determined by moistening a piece of paper with the outflowing liquid, and if the paper gives no trace of grease the operation may be considered as finished. The valves in pipes M M are now closed, as is also the valve in pipe F, and the valve in pipe G is opened, whereby live steam will flow into the apparatus and through the exhausted, or practically exhausted, material, thereby dissolving out any traces of soluble material and escapes by pipes H and led thereby to a condenser. The cover 0, as well as the lower cover or bottom 0, if desired, are now removed and the exhausted matter allowed to fall out of the receiver 13. The cover C is then replaced, and the apparatus is then ready for another charge.

\Ve would state that it is not absolutely necessary to use the interior receiver B, as the same might be dispensed with, or the same might be replaced by a perforated cage. A pipe N may be used to replace the pipe G in the event of the omission of receiver B.

L indicates a cock applied to receiver A.

The duration of the process will of course vary according to the character of the material operated upon.

lVe claim and desire to secure by Letters Patent In an extracting apparatus of the character described, the combination with an outer casing or receiver A, of a second, perforated receiver B arranged therein and of less diameter to leave an intermediate space between the two, said second receiver making a tight joint with the outer receiver at top and bottom, detachable covers closing the upper and lower ends of the receiver B, an inlet-pipe for solvent leading into the receiver B, a second inlet-pipe for solvent leadin into the receiver A, a steam-pipe leading into the receiver A, a heating-pipe leading into and through the receiver B, an outlet-pipeleading from the receiver 1- and an outlet-pipe for extracted matter leading from the lower end of receiver A, said pipe having a transparent section, all arranged as and for the purpose specified.

In testimony that we claim the foregoing we have hereunto set our hands this 29th day of September, 1896.
